ABAP code example for Function Module ISU_SAMPLE_0040

The ABAP code below is a full code listing to execute function module ISU_SAMPLE_0040 including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

DATA:
it_t_fkkopw  
 
 TYPE STANDARD TABLE OF FKKOPW,"TABLES PARAM

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_i_fkkko
 
 TYPE FKKKO ,
it_t_fkkopw
 
 TYPE STANDARD TABLE OF FKKOPW ,
wa_t_fkkopw
 
 LIKE LINE OF it_t_fkkopw,
ld_i_fkkop
 
 TYPE FKKOP ,
ld_i_actvt
 
 TYPE TACT-ACTVT .


ld_i_fkkko = 'Check type of data required'. 

"populate fields of struture and append to itab
append wa_t_fkkopw to it_t_fkkopw.
ld_i_fkkop = 'Check type of data required'.

SELECT single ACTVT 
  FROM TACT 
  INTO ld_i_actvt.
